The present invention relates to an air conditioner for cleaning or humidifying the air. Air weapon according to the embodiment of the present invention, the air blowing fan to the flow of air upwardly from the lower side and the air passage of the annular to the flow of air discharged from the blower motor and a blower fan for rotating the ventilation fan is formed blower motor a support ventilation housing, and is coupled to the air flow housing top is arranged on the lower side of the blower housing comprises a flow guide that the ventilation fan bottom is accommodated, the air blowing fan that is, the hub which the axis of rotation of the blower motor coupled to the center, the hub linearly arranged apart from each other on the lower side, and a plurality of blades provided between the shroud and the hub and the shroud is formed with a suction port through which air is drawn into the center portion, and the hub is extended to the direction toward the peripheral edge in the vertical cross-sectional view of ( a) is formed to be inclined to the rotation axis, the shroud is formed to be inclined and the peripheral edge is directed towards a linear (C extending direction), the axis of rotation in longitudinal section, the transmitting Style housing, is arranged in the center of the blower body, a ventilation body of cylindrical shape forming an air flow body and the air passage, and includes a motor cover of the bowl-shaped blown motor is inserted, a motor cover, toward the outer peripheral edge of the hub never met and the straight line (a), is arranged so that the bottom is lower than the outer peripheral edge of the shroud.
